Tendon transfer
Neurapraxia presents with muscle weakness and numbness.
False
Axonotmesis results in complete loss of motor, sensory, and sympathetic function.
False
Neurotmesis is characterized by anesthesia (no pain) and muscle wasting.
True
NCS is commonly used for diagnosis of peripheral nerve injuries but not for treatment monitoring.
